new exhaust system
got the beast back after install w/custom welder-exhaust house: BSM Hot Rods of Lowell, MA.
I used 3" turbo flange into a Magnaflow 3" in/out round with 18" body, into a 3" mandrel bend 3" radius bend "U", into a Borla 3" in/out round with a 15" body, into the 3" tail pipe (as seen on the picture w/bumper).
sound is deep and low... very quiet, louder than stock, not as loud as the FabSpeed single I removed. very pleased with the result and the 'artist' (Jason Betty of BSM).
pictures below. still debating whether to black ceramic coat the entire system, less the tip. I think it looks 'like somethings doing inside there', but maybe best to 'hide in black'....
opinions/feedback?

Magnaflow by itself wasn't quiet enough (for me), and the Borla (which had less siliencing potential) surely wouldn't have been enough. I'm very happy with what I have now. also, final black out photo:

PT-
'seat of the pants'... seems the same as the FabSpeed alone. certainly MUCH better than gutted-cat/stock-muf. I will be on the Dyno in Nov (valve adjust, pre-emission test, etc.) and will let you know if there is positive/negative to this set-up power-wise.
